The Twilight Brigade members are on a mission to find the Key of the Twilight, however, the TAN guild opposes this because they want Ovan's character data possibly because of his device in his arm and will stop at nothing to keep the Twilight Brigade from their goal. But possibly the reason is because Ovan is after it.

Their current mission is to find the 6 virus cores before TAN does. Haseo has the green virus core and the purple core, Shino has the red, Sakisaka the Yellow, Ovan the grey, and Gord has the blue one. There is a Lost Ground with 5 towers, where the Brigade used the supposedly-unusable virus cores. When the five are used it transports them to the tower above the 5 small towers to where they can find the last virus core.

This mission, unfortunately, was just a trap made by the members of TAN in order to investigate Ovan's strange character data. With Ovan gone, and no sign of the Key of the Twilight, the Twilight Brigade quickly breaks apart. B-set and Gord quit the game entirely, and Sakisaka and Tabby quit the guild, even though Tabby is still hopeful things will pick up. Shino goes into 'mourning' over Ovan, as it has been hinted that their relationship is that of more than friends, with Haseo by her side supporting her. However, even this is quickly shattered, as Shino is soon after killed within the game. What's even more alarming is that Haseo can't contact her in real life.
